Is this the same as jq on the command line?

Yes. It is jq 1.8 itself, so built-ins, error messages and output formatting match the jq command. Options like -c, -r, -s and -S are available as toggles.

Can I process several JSON documents at once?

Yes. Put them one after another in the input, as in a JSON Lines file. Turn on Slurp to read them into a single array first.

Why does my filter show an error?

The message comes straight from jq. Common causes are indexing a value of the wrong type, such as .name on an array, or a typo in the filter.
